DRAFT APPLIANCE FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent NO. 789,314, dated May 9, 1905,

Application filed December 19, 1904. Serial No. 287,511.

To all whom, it may concern:

Be it known that I, SILAs E. BAILOR, a citizen of the United States, residing at Tarkio, in the county of Atchison and State of Missouri, have invented a new and useful Draft Appliance for Cultivators, of which the following is a specification.

This invention relates to a draft appliance for cultivator-s, and particularly to that class of cultivators which are supported upon wheels and which are adapted to cultivate two rows of plants simultaneously.

The object of the present invention is to improve the draft attachment so as to equalize the strength upon the draft-animals, three of which are preferably employed.

The invention consists in the improved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of embodiment of the invention, it being, however,

understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modifications may be resorted to within the scope of the invention when desired.

The single view in the drawing hereto attached represents a perspective view of a cultivator-frame equipped with a draft-equalizing device in accordance with the invention.

The cultivator-frame includes the axle 1, a front member 2, suitably spaced from said axle, and a pair of thills 3 3, which are mounted upon the axle 1 and cross-piece 2. The latter is provided at or near the ends thereof with depending yokes or brackets 4 4:, the lower ends of which are connected with the axle l by means of inclined braces 5, whereby the frame construction is reinforced. The frame has been shown as including a cross member 6, supported upon the sills and having depending links 7 connected with the yokes 8, to which in practice the cultivator-gangs are attached. The cross-piece 2 of the frame is provided with upwardly-extending brackets or clips 9, in which are pivotally mounted the equalizing-levers 10. Connected with the outer ends of said levers by means of links 11 are chains 12, which are guided under sheaves 13, supported at the lower ends of the yokes or brackets 4c, and having swingletrees 14 attached at their front ends.

The inner ends of the equalizing-levers 1O 10 are connected by means of a chain or equivalent flexible member 15, which is guided under a sheave 16, journaled in a block or casing 17, with which is connected a chain or flexible member 18, which is guided under a sheave 19, journaled in a yoke or bracket 20, which is connected with the under side of the cross-bar 2 of the frame. The chain 18 carries at its front or free end a swingletree 21. 1t will be observed that the latter swingletree is disposed between the gang-carrying yokes or arches 8 8, while the swingletrees 14: are mainly supported adjacent to the outer sides of said arches, thus permitting the mid dle draft-animal to walk between the rows that are to be cultivated, while the outer draft-animals will walk adjacent to the outer sides of the rows.

It will be observed that by properly proportioning the equalizing-levers the strain upon the draft-animals will be perfectly equalized. It will also be seen that the connection between the equalizing-levers by means of the chain 15 passing over the pulley 16 will operate independently of the connection of said equalizing-levers with the member to which the middle draft-animal is attached. In this manner a perfect equalization of the draft may be obtained.

Having thus described the invention, what isclaimed is- 1. A cultivator-frame including an axle, a front cross-bar, brackets depending from said cross-bar and braces connecting the lower ends of said brackets with the axle, in combination with clips mounted upon the front cross-bar, equalizing-levers supported in said clips, a flexible member connecting the inner ends of the equalizing-levers, a sheave mounted in a frame or block and supported upon said flexible member, and suitably-guided means for applying draft to the sheave-carrying block and to the outer ends of the equalizing-levers.

2. A cultivator-frame including an axle, a front cross-bar spaced from said axle, brackets depending from the ends of said cross-bar, sheaves journaled at the lower ends of said brackets, braces connecting the lower ends of said brackets With the axle, a sheave-carrying bracket depending from the central portion of the front cross-bar, and suitably-supported arches disposed intermediate the central and the end brackets depending from the front cross-piece, in combination With suitablysupported equalizing-levers, flexible members connected With the outer ends of said levers, guided under the sheaves in the brackets at the ends of the front cross-bar and adapted for the attachment of draft, a flexible member connecting the inner ends of the equalizing-levers, a sheave mounted in a frame or block supported upon said flexible member, and a flexible member connected with the sheave-carrying block and guided under the sheave in the bracket depending from the central portion of the front cross-bar and adapted for the attachment of draft.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.
